Description
Technical field
The present invention relates to a kind of road indicating device, relate in particular to a kind of Portable multistage warning being applicable to night
Device.
Background technology
Along with developing rapidly of motor vehicles, the various faults occurred because of motor vehicles and vehicle accident are the most increasingly
Many, when people are when processing various faults and vehicle accident, in order to vehicular traffic and pedestrian being warned or in order to effectively
The protection scene of a traffic accident, needs quickly to arrange warning regional extent, particularly the vile weather such as night, rainy day or dense fog
Time, if warning mark can not quickly be arranged, and easily there is second accident, the life security of serious threat people and property peace
Entirely.
In order to solve the problems referred to above, Chinese patent literature CN200979776Y discloses a kind of multifunction combined warning dress
Put, including main body, in described main body, be provided with power supply and luminous body, be provided with warning rope, this warning in the side, top of described main body
One end of rope is connected with the rotating shaft being fixed in main body, and the other end connects a font reflecting pole, font reflecting pole and main body it
Between socket-connect, the opposite side in main body is provided with warning rope or is provided with the warning panel writing different caution slogans.The most above-mentioned patent
Multi-functional combined signalling device described in document, during use, separates light emitting host and luminous daughter, utilizes warning rope quickly
Delineation alert zone, pull-out warning panel, warning vehicular traffic or pedestrian；Utilize linking socket by light emitting host and reflective when carrying
Font set loads, and reduces its volume.But above-mentioned multi-functional combined signalling device has the following disadvantages: in this warning
In device, in warning rope is by main body after pull-out, mainly by both main body and daughter reflecting pole, its pulling force is formed
Certain alert zone, i.e. its one end are fixed by main body, and its other end is fixed by daughter reflecting pole, but daughter reflecting pole weight
Amount is relatively light, is easily blown down by strong wind or passing vehicle, when special bad weather or Vehicle Speed are very fast, so that should
The prompting weak effect of device, is still susceptible to second accident, it is impossible to ensure life security and the property safety of personnel.
In order to solve the problems referred to above, Chinese patent literature CN201522785U discloses a kind of Portable parking security alarm
Device, it includes type inflatable image, warning box, and adding in type inflatable image has implant, and the foot of type inflatable image is even
Having iron plate, type inflatable image connects the case lid of warning box by magnetic sheet, and described warning box is divided into two-layer, and one layer stores for instrument
Layer, another layer is key-course, and described instrument storage layer is embedded with Telescopic handle and the Triangular warning sign of two band iron plates, described
Key-course includes socket, alarm, control switch, accumulator, LED, and accumulator connects alarm respectively, controls switch and insert
Seat, socket connects several LED by plug, and the panel of described key-course has two jacks.This Portable parking safety
Alarm device, when daytime uses, inflates and fills completely by image, for preventing people from meeting wind by chance, fills chemical industry sponge and rise in image
Fixation, is connected on warning box by Magnet, places the distance that specifies from car of the tailstock, with image containing reflectorized material
Triangular warning pattern point out vehicle later further；When night uses, first warning box is placed on the tailstock from car specify away from
From, to open warning box, take out instrument storage layer, Telescopic handle is inserted in jack, pull-out pull bar, to certain altitude, then leads to
Cross the LED lamp back side Magnet LED to be pull-in on iron plate, and the triangle warning plate containing reflectorized material is pull-in on ferrum simultaneously
On plate, plug LED plug, turn on the power switch, open alarm switch and just can normally employ.
There is following problem in the Portable parking safety alarm device described in above-mentioned patent documentation: this device is by day
Time mainly warned by type inflatable image, and be by pulling out pull bar in warning box in the evening, make lED lamp and
Triangle warning plate is pull-in on iron plate, then switch power supply, makes LED and warning sign is glittering warns, and therefore, uses
Alarming device is changed in the replacement that person need to be concerned about according to day and night, uses and very inconvenient does not saves worry；And can only
Realize one-level warning, when bad weather, may exist and have little time brake until driver sees warning clearly, thus lead
Cause the generation of second accident.Additionally, the inflatable partners on either daytime, or the pull bar in evening, use the most particularly troublesome,
The most inflatable doll, needs inflation before using, need again ventilation to fold after using, and easily damaged.
Summary of the invention
To this end, the technical problem to be solved be safety alarm device of the prior art in-convenience in use,
Can only carry out one-level warning reliability low, and then provide a kind of easy to use, the Portable multistage with multistage alarming effect is alert
Showing device.
